'r so sr HARRY G. IPOTTLE, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS/TO THE L'UDLOW TYPOGRAPH COMPANY, or orrroeeo, iLLmois, A CORPORATION or'k ILLINOIS.

Tol all whom tpmag/ concern 'Be it known that I, HARRY G. POTTLE, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Typograph Mechanism, of

which the following is a specification, the e, principle of the invention being herein ex- Y called Ludlow V,typograph plained and the best mode in'which Il have contemplated applying that principle, so as to distinguish itfrom other inventions.

The present improvements, relating, as indicated, to typograph mechanism, have more particular regardto holders for matrix bars such as are employed in Lthe sosee U. S. Letters :PatentA No'. 1,266,15'6-to William A. Reade', dated `May 14;,"1918). In suchtypograph the 'holder is an independent member arranged tof receive and: hold a number of detachedfmatrix bars in selected relation, therebyY formingy va' composite matrix apart from, but adapted to co-operate with, a mold when said holder is temporarily securedto a suitable supporti vThe detached matrix bars, or matrices as they are ordinarily called, are in eifectplates or blocks of uniform length and height, but of varying width, to accommodate character mpressions of correspondingly varying width. The character impressions are struck or driven in the bottom of recesses cut in .what may be called the lower edges of the bars, and it is the practice, for reasons that need not be explained, to center suchcharacters onv a transverse medianline. Accordingly, an assemblage of matrices selected from the same font will have the lower edges ofthe character impressions properly aligned, but when it is desired to set -up matter in which some of the letters orl other characters are displaced above or below the normal line, a special matrix obviously requires to be provided. Y j

The object of the present invention is to provide 4a holder of the character described, wherein the matrices maybe individually displaced transversely of such holder so as to locate the character impression either above l or below the normal alignment, 'as may bedesired. y

To vthe accomplishment of the foregoing and related ends, the invention, then, con

TYPO GRAPH MECHANISM.

Specification of Letters Patent.

The holder, in form illustrated, comprises two end piecesv Patented May 2,1922.

Application led August 23, 1919. Serial No; 319,397.

sists of the means lhereinafter fully Vdescribed and particularly pointed out in the claims, the annexed drawing and the following description settin forth in detail certain mechanism embo ying 'the invention, such disclosed means constituting, how'- ever, butone of various mechanicalk forms in whichtheprinciple of the invention may f be used.

In .saidY annexed drawingi- Y v Fig. l is a top plan view of "a holder such as is employed inthe Ludlow typograph, a portionof one side'thereof being broken away. to show the interior construction;

is a bottom plan view of such holder, showingaseries of matrix bars held therein; Figs. 3 and l are transverse sections of such holder and matrix bars, the lplanes lof the sections being respectively indicated by the lines kn--ande-l',Fig. 2; and Fig. 5 illustrates an impression Or'print made from a lcomposite matrix assembled in the present improved holder.

the: commercial structural l and 2 secured to side members 3 and 4: of sufficient length to`Y provide anl vopening somewhat larger thanv the maximum 'length of the slug which it is desired to cast. Slid-V ably mounted between said side members, at one end of the holder, is a clamp member in the form of a block 5 that is engaged by the threaded portion of a screw 6 rotatably secured in the adjacent end piece 2, and provided with a knurled head. Obviously by rotating such screw thebl'ock 5 can be advanced or retracted to clamp, or release yas y desired, the assembled matrix bars 7 as shown in Fig. 2.

The latter are of the general form illustrata ed inV Figs. 3 and 4, the character impressions l8 beingstruck or driven in the bottom of recesses 9 out `in the lower edges of said bars. yThe upper portions of the matrix bars project laterally/in the form of ears l0 that are adapted to rest on'the side pieces ,tate the insertion of the matrix bars in the holder, theinnerface of at least one thereof is slightly beveled or flared upwardly, a

close 'tffbeing secured, however, between IOO their lower edges and the bars so as toy insure the correct alignment of the latter in a horizontal plane. The extent of the assembled lineot bars or matrices can be readily determined by graduations 11 on the upper face of the side piece 4i, and if necessary the line may be iilledout, as well as proper spaces provided, by the insertion of blankfbars, as will be readily understood. When a line of proper length has beenvassembled, the bars are clamped longitudinally ofthe holderby turning thel screw 6, and the holder may then be placed in the typographmachine and a slug cast, takingfthe impression of the assembled character impressions on the under faces of the bars, as need not be further explained.

inthe present improved holder, instead of A vboth side` pieces 3 anda having solid inner Vfaces, the one such piece 3 is provided .with a series of springspressed` plungers 12, as besty shown in Figs. l, 3 and e, the inner ends of which normally project an equaldistance withinfthe opening betweenthe side members so. as to` leave just thev proper space for: the insertion of the matrixbars 7, 'further movement being prevented by heads 13 ony such plunger. Y Theplungers, aswell as the springsllhwhich thus normally position the same, are retained in place in the side piece .by means `of ya plate l5 that closes Y the vopenings in 1 which such plungersfand springs are received.

When nowrit isdesired todisplace any Vparticular character impression, with Y re' `spect tothenormal line, by inserting a plate or l liner 16 votproper thickness, and-'of a length corresponding.. to the. width ofthe matrix bar or bars to be displacedthe latter may obviously. be shoved over into contact with the fiat inner face of side piece 3, or toany position short of such contact, within `the limit of movementof the plun gers 12'. The effect of such displacement is showny in Fig. 5, illustrating` the word T1-1E set up with the second` and thirdl lettersalignedy with an upper edge ofthe firstletter. The utility of the present holder in setting up price marks, applying letters or numerals as suiiixes, etc., will be readily apparentk from the foregoing.

It will be understood that the plungers 12 are closelyenough spaced to insurethe engagement with one or lmore thereof by each bar, however thin or narrow the edge of the latter. The contacting ends ot said plungers are preferably rounded slightly, as shown, so as not to interfere with the adjustmentoi'1 the bars longitudinally of the `opening in the holder in the normal position off said plungers.V

Other modes of applying the principle, of

my inventionmay be employed instead of theone explained, change being made as re-r gards the mechanism herein disclosed, pro-y vided the means stated yby any Yof the following ciaims or the equivalentof such stated means be employed.
